The Complete Handbook of Lychees

Chapter 1: Understanding Lychees

The lychee (Litchi chinensis) is a tropical evergreen tree that produces a fruit we often describe as sweet and floral, but a professional cannot afford to think of it only in terms of taste. At its core, the lychee is a ticking biological clock. From the moment it is harvested, it is a living, respiring organism that is rapidly losing water, converting its sugars to alcohol, and becoming increasingly vulnerable to fungal attack. To work with the lychee - whether as a grower, a retailer, or a chef - is to engage in a race against that clock. Everything of practical importance about the lychee stems from this one, non-negotiable fact: it is a perishable commodity that was not designed for the modern supply chain. It was designed to be eaten by a bird on the same day it was picked.

Let's start with the physical object itself. When you hold a lychee, you are holding three distinct layers. The outermost layer, the pericarp or shell, is a thin, leathery skin that is a brilliant red in a fresh, high-quality cultivar. This is the fruit's first line of defense, but it is also its most profound weakness. The pericarp is not a solid barrier. It is filled with microscopic pores called lenticels, through which the fruit can 'breathe' and lose water at an alarming rate. Once a lychee is removed from the tree, that water loss begins immediately, and the consequences are visible within
